Description

液晶材料貯藏容器 Liquid crystal material storage container

本發明係關於一種液晶材料貯藏容器。 The invention relates to a liquid crystal material storage container.

用於液晶顯示裝置等之液晶材料係混合有複數種化合物之液狀組成物，以往，以收容於玻璃瓶等之狀態進行保管或搬送。另一方面，近年來，為了能夠收容大量之液晶材料，而使用金屬製之大型貯藏容器。例如於專利文獻1中，揭示有由保護氣體置換內部氣體而將液晶材料封入之鋼鐵製貯藏容器。如此，藉由將貯藏容器設為金屬製，而相較於由玻璃形成之情形更容易大型化。 Liquid crystal materials used in liquid crystal display devices, etc., are liquid compositions in which a plurality of compounds are mixed. Conventionally, they have been stored or transported in a state of being housed in a glass bottle or the like. On the other hand, in recent years, in order to be able to accommodate a large amount of liquid crystal materials, large metal storage containers have been used. For example, Patent Document 1 discloses a storage container made of steel in which the internal gas is replaced by a protective gas and the liquid crystal material is enclosed. In this way, by making the storage container made of metal, it is easier to increase in size than when it is made of glass.

[專利文獻1]日本特開2005-157361號公報 [Patent Document 1] Japanese Patent Application Laid-Open No. 2005-157361

然而，若容器大型化，則伴隨容器重量增加而使容器傾斜等作業變得困難。其結果，存在無法將貯藏於內部之液晶材料全部取出至外部而導致液晶材料之一部分殘存於貯藏容器內部造成浪費之情形。例如於專利文獻1中，具有利用自上方延伸設置至容器本體底部附近之液體輸送管將液晶材料取出至外部之構造。然而，於液體輸送管與容器本體部之底部之間形成有一定間隙，於專利文獻1所揭示之貯藏容器中，液晶材料殘存於容器本體底部之較大範圍。 因此，根據專利文獻1所揭示之貯藏容器，難以自容器本體取出較多之液晶材料，存在液晶材料之浪費變多之問題。 However, if the container is enlarged, work such as tilting the container becomes difficult as the weight of the container increases. As a result, it is impossible to take out all the liquid crystal material stored inside to the outside, and a part of the liquid crystal material remains inside the storage container, causing waste. For example, in Patent Document 1, there is a structure in which the liquid crystal material is taken out to the outside using a liquid delivery tube extending from above to near the bottom of the container body. However, a certain gap is formed between the liquid delivery pipe and the bottom of the container body. In the storage container disclosed in Patent Document 1, the liquid crystal material remains in a large area of the bottom of the container body. Therefore, according to the storage container disclosed in Patent Document 1, it is difficult to take out a large amount of liquid crystal material from the container body, and there is a problem that the waste of liquid crystal material increases.

本發明係鑒於上述問題點而完成者，其目的在於提供一種能夠減少難以自容器本體取出之液晶材料而有效利用液晶材料的液晶材料貯藏容器。 The present invention was made in view of the above-mentioned problems, and its object is to provide a liquid crystal material storage container that can reduce the liquid crystal material that is difficult to take out from the container body and effectively utilize the liquid crystal material.

本發明採用以下構成作為用以解決上述課題之手段。 The present invention adopts the following constitution as a means to solve the above-mentioned problems.

第1發明係能夠貯藏液晶材料之液晶材料貯藏容器，且具有：容器本體，其於上部具有開口部，且於底部之一部分具有朝向下方凹陷之凹部；及蓋部，其能夠將上述容器本體之上述開口部開閉。 The first invention is a liquid crystal material storage container capable of storing liquid crystal materials, and has: a container body having an opening at the upper part and a concave part recessed downward at a part of the bottom; and a lid part capable of holding the container body The opening is opened and closed.

第2發明係在上述第1發明中，採用如下構成，於俯視下上述容器本體之上述底部為圓形，且將上述凹部配置於底部中央。 The second invention is the above-mentioned first invention, adopting a configuration in which the bottom of the container body is circular in plan view, and the recess is arranged in the center of the bottom.

第3發明係在上述第1或第2發明中，採用如下構成，上述容器本體之上述底部之上表面設為隨著朝向上述凹部下降之傾斜面。 According to a third invention, in the above-mentioned first or second invention, a configuration is adopted in which the upper surface of the bottom of the container body is an inclined surface that descends toward the recessed portion.

第4發明係在上述第1至第3任一發明中，採用如下構成，具有固定於上述容器本體之外壁面且於上述容器本體之外側覆蓋上述凹部之保護壁。 The fourth invention is in any one of the first to third inventions, and adopts a configuration including a protective wall fixed to the outer wall surface of the container body and covering the recessed portion on the outer side of the container body.

第5發明係在上述第4發明中，採用如下構成，上述保護壁係自側方包圍上述凹部之全周並且自上述容器本體之上述底部之外壁面延伸至較上述凹部之下端更下方的圍壁。 The fifth invention is in the fourth invention described above, and adopts a configuration in which the protective wall surrounds the entire circumference of the recessed portion from the side and extends from the outer wall surface of the bottom of the container body to a circumference below the lower end of the recessed portion wall.

第6發明係在上述第1至第5任一發明中，採用如下構成，上述容器本體具有：圓筒狀之中央部，其係將上下端設為開口端；上端部，其具有上述開口部，並且與上述中央部之上端接合；及下端部，其具有上述底部，並且與上述中央部之下端接合。 The sixth invention, in any one of the first to fifth inventions, has the following configuration. The container body has a cylindrical center portion with upper and lower ends as open ends; and an upper end portion with the openings. , And joined with the upper end of the above-mentioned central part; and a lower end part having the above-mentioned bottom and joined with the lower end of the above-mentioned central part.

第7發明係在上述第1至第6任一發明中，採用如下構成，上述容器本體係由以鈦為主成分之素材形成。 The seventh invention is that in any one of the first to sixth inventions, the above-mentioned container system is formed of a material whose main component is titanium.

根據本發明，於容器本體底部形成有朝向下方凹陷之凹部。該凹部係向較周圍之面(底部之上表面)更下方凹陷而形成。因此，殘存於容器本體底部之液晶材料積存於凹部。即，根據本發明，能夠將殘存於底部之液晶材料局部地聚集至凹部。因此，根據本發明，與液晶材料殘存於容器本體底部之較大範圍的情形相比，容易自容器本體取出殘存之液晶材料。由此，根據本發明，能夠減少難以自容器本體取出之液晶材料而有效利用液晶材料。 According to the present invention, a concave portion recessed downward is formed on the bottom of the container body. The recess is formed by being recessed below the surrounding surface (the upper surface of the bottom). Therefore, the liquid crystal material remaining at the bottom of the container body is accumulated in the concave portion. That is, according to the present invention, the liquid crystal material remaining at the bottom can be locally collected in the concave portion. Therefore, according to the present invention, it is easier to take out the remaining liquid crystal material from the container body compared to a case where the liquid crystal material remains in a larger area at the bottom of the container body. Therefore, according to the present invention, it is possible to reduce the liquid crystal material that is difficult to take out from the container body and effectively use the liquid crystal material.

Furthermore, in the following drawings, in order to make each member a recognizable size, the scale of each member is appropriately changed.

圖1係能夠貯藏液晶材料之本實施形態之液晶材料貯藏容器1之外形圖，(a)係俯視圖，(b)係側視圖。又，圖2係本實施形態之液晶材料貯藏容器1之縱向剖面圖。如該等圖所示，本實施形態之液晶材料貯藏容器1具備容器本體2、腳部3(保護壁)、蓋部4、蓋部用封材5、及緊固部6。 Fig. 1 is an external view of the liquid crystal material storage container 1 of this embodiment capable of storing liquid crystal materials, (a) is a plan view, and (b) is a side view. 2 is a longitudinal cross-sectional view of the liquid crystal material storage container 1 of this embodiment. As shown in these figures, the liquid crystal material storage container 1 of the present embodiment includes a container main body 2, a leg portion 3 (protection wall), a lid portion 4, a lid portion sealing material 5, and a fastening portion 6.

容器本體2設為於上部具有開口部之有底圓筒狀之容器形狀，能夠於內部收容液晶材料。該容器本體2係將以圖2所示之軸芯L為中心軸之圓筒狀之側壁部2a、將側壁部2a之下端封閉之底部2b、及與側壁部2a之上端連接之上壁部2c一體地連接而形成。 The container body 2 has a bottomed cylindrical container shape with an opening at the upper part, and can accommodate liquid crystal materials inside. The container body 2 has a cylindrical side wall portion 2a with the shaft core L shown in FIG. 2c is formed by integrally connecting.

底部2b係外緣部沿著圓筒狀之側壁部2a之俯視圓形之圓板狀的部位，且於該俯視下之中央部具有凹部2b1。該凹部2b1係以相對於周圍之區域朝向更下方凹陷之方式形成，設為將殘存於底部2b上之液晶材料聚集之部位。此種凹部2b1形成於在俯視下與設置於蓋部4之下述液體輸送管4b3重疊之位置，俯視形狀設為直徑略大於液體輸送管4b3之圓形狀。又，凹部2b1係設為藉由以俯視下之中心位置位於最下方之方式朝向該中心位置縮窄而內壁面成為錐形面之形狀。如圖2所示，此種凹部2b1之內表面及外表面設為無折曲部位之圓滑面，與凹部2b1之周圍之面平滑地連接。藉由設為此種凹部2b1之內表面及外表面不折曲地與凹部2b1之周圍之面平滑地連接之構造，而防止較大之應力局部作用於凹部2b1或凹部2b1之邊界區域，從而提高容器本體2之強度。 The bottom portion 2b is a circular disk-shaped portion in a plan view along the cylindrical side wall portion 2a with its outer edge portion, and has a recess 2b1 in the center portion in the plan view. The concave portion 2b1 is formed to be recessed further below with respect to the surrounding area, and is set as a place where the liquid crystal material remaining on the bottom portion 2b gathers. Such a recessed portion 2b1 is formed at a position overlapping the liquid delivery pipe 4b3 provided in the cover 4 in a plan view, and the shape in a plan view is a circular shape with a diameter slightly larger than the liquid delivery pipe 4b3. In addition, the concave portion 2b1 has a shape in which the inner wall surface becomes a tapered surface by narrowing toward the center position so that the center position in a plan view is located at the bottom. As shown in Fig. 2, the inner and outer surfaces of the recess 2b1 are formed as smooth surfaces without bending portions, and smoothly connect with the surrounding surfaces of the recess 2b1. The structure in which the inner and outer surfaces of the concave portion 2b1 are smoothly connected to the surrounding surfaces of the concave portion 2b1 without bending can prevent a large stress from locally acting on the concave portion 2b1 or the boundary area of the concave portion 2b1. Improve the strength of the container body 2.

凹部2b1之周圍區域2b2係俯視下包圍凹部2b1之部位，且上表面設為隨著朝向凹部2b1而連續地下降之傾斜面。該周圍區域2b2之上表面設定為與凹部2b1之內壁面相比而相對於水平面之傾斜角度較小。即，周圍區域2b2之上表面與凹部2b1之內壁面相比，設為平緩之傾斜面。此種凹部2b1之周圍區域2b2係將殘存於底部2b之液晶材料朝向凹部2b1引導。再者，周圍區域2b2之上表面之傾斜角度無須於整個周圍區域2b2一致。例如亦可使俯視下周圍區域2b2之 徑向外側之區域(即，靠近側壁部2a之區域)相對於水平面之傾斜角度大於徑向內側之區域(即，靠近凹部2b1之區域)相對於水平面之傾斜角度。如此，在周圍區域2b2使上表面之傾斜角度部分地變化之情形時，理想的是傾斜角度之變化連續。藉由使傾斜角度之變化連續，能夠防止於周圍區域2b2產生折曲之部分。 The surrounding area 2b2 of the recessed portion 2b1 is a portion surrounding the recessed portion 2b1 in a plan view, and the upper surface is an inclined surface that continuously descends toward the recessed portion 2b1. The upper surface of the peripheral area 2b2 is set to have a smaller inclination angle with respect to the horizontal plane than the inner wall surface of the recess 2b1. That is, the upper surface of the peripheral area 2b2 is a gentle slope surface compared with the inner wall surface of the recessed part 2b1. The surrounding area 2b2 of the concave portion 2b1 guides the liquid crystal material remaining on the bottom portion 2b toward the concave portion 2b1. Furthermore, the inclination angle of the upper surface of the surrounding area 2b2 does not need to be consistent with the entire surrounding area 2b2. For example, the inclination angle of the radially outer area of the peripheral area 2b2 (that is, the area close to the side wall portion 2a) with respect to the horizontal plane in plan view is larger than the radially inner area (that is, the area close to the recess 2b1) with respect to the horizontal plane. slope. In this way, when the inclination angle of the upper surface is partially changed in the surrounding area 2b2, it is desirable that the change in the inclination angle is continuous. By making the change of the inclination angle continuous, it is possible to prevent a bent portion from being generated in the surrounding area 2b2.

如此，容器本體2於底部2b之一部分具有朝向下方凹陷之凹部2b1。因此，殘存於底部2b之液晶材料容易聚集至凹部2b1。因此，能夠將殘存於底部2b之液晶材料局部地聚集至底部2b之一部分。 In this way, the container body 2 has a concave portion 2b1 recessed downward in a part of the bottom portion 2b. Therefore, the liquid crystal material remaining on the bottom portion 2b is likely to gather in the concave portion 2b1. Therefore, the liquid crystal material remaining on the bottom 2b can be locally collected to a part of the bottom 2b.

再者，於自容器本體2取出液晶材料之後，殘存於底部2b之液晶材料花費一定時間，沿著上表面如上述般傾斜之周圍區域2b2而聚集至凹部2b1。因此，由凹部2b1所包圍之空間(液晶材料積存之空間)之容積理想的是以如下方式設定，即，於藉由表面張力暫時附著於周圍區域2b2之液晶材料沿著周圍區域2b2之傾斜引導並聚集至凹部2b1之情形時，能夠收容所聚集之所有液晶材料。藉由表面張力暫時附著於周圍區域2b2之液晶材料之量可基於周圍區域2b2之傾斜角度、周圍區域2b2之表面性、及液晶材料之黏度等預先藉由實驗等進行估計。 Furthermore, after taking out the liquid crystal material from the container body 2, the liquid crystal material remaining on the bottom 2b takes a certain time to gather in the concave portion 2b1 along the peripheral area 2b2 inclined as described above on the upper surface. Therefore, the volume of the space enclosed by the recess 2b1 (the space where the liquid crystal material accumulates) is ideally set in such a way that the liquid crystal material temporarily attached to the surrounding area 2b2 by surface tension is guided along the inclination of the surrounding area 2b2 When it is gathered in the recess 2b1, it can contain all the liquid crystal materials gathered in the house. The amount of liquid crystal material temporarily attached to the surrounding area 2b2 by surface tension can be estimated in advance by experiments based on the tilt angle of the surrounding area 2b2, the surface properties of the surrounding area 2b2, and the viscosity of the liquid crystal material.

容器本體2之上壁部2c具有與側壁部2a之上端連接之肩部2c1、及配置於俯視之中央且自肩部2c1朝向上方突出之口部2c2。口部2c2設為上下端設為開放端之圓筒狀，由該口部2c2所包圍之區域設為容器本體2之開口部(以下，稱為開口部2d)。即，容器本體2於上部具有用以存取液晶材料之開口部2d。 The upper wall portion 2c of the container body 2 has a shoulder portion 2c1 connected to the upper end of the side wall portion 2a, and a mouth portion 2c2 disposed in the center of the plan view and protruding upward from the shoulder portion 2c1. The mouth portion 2c2 is formed in a cylindrical shape whose upper and lower ends are open ends, and the area surrounded by the mouth portion 2c2 is formed as an opening portion of the container body 2 (hereinafter, referred to as an opening portion 2d). That is, the container body 2 has an opening 2d at the upper part for accessing the liquid crystal material.

又，於口部2c2之上端部形成有用以使蓋部4抵接之凸緣2c3。凸緣2c3係以俯視下包圍開口部2d之方式配置，且係相對於口部2c2之下部向開口部2d之徑向外側突出而形成。於該凸緣2c3，在開口部2d之圓周方向上離散地形成有複數個(於本實施形態中為4個)上下貫通之螺栓插通孔2c4。又，於凸緣2c3之上表面形成有供蓋部用封材5嵌合之環狀之槽部。 In addition, a flange 2c3 for abutting the lid 4 is formed at the upper end of the mouth 2c2. The flange 2c3 is arranged so as to surround the opening 2d in a plan view, and is formed by protruding outward in the radial direction of the opening 2d from the lower part of the opening 2c2. In the flange 2c3, a plurality of (four in this embodiment) bolt insertion holes 2c4 penetrating up and down are formed discretely in the circumferential direction of the opening 2d. In addition, an annular groove into which the lid sealing material 5 is fitted is formed on the upper surface of the flange 2c3.

此種容器本體2之大小並無特別限定，例如可設定為以10L液晶材料成為裝滿之容量。例如於設為以10L液晶材料成為裝滿之容量之情形時，可想到將容器本體2之外徑尺寸設為200mm，且將高度尺寸設為300mm左右。但是，容器本體2亦充分能夠設為可收容100L液晶材料之大小。 The size of the container body 2 is not particularly limited. For example, it can be set to a full capacity with 10L liquid crystal material. For example, when 10L of liquid crystal material is used as a full capacity, it is conceivable to set the outer diameter of the container body 2 to 200 mm and the height to about 300 mm. However, the container main body 2 can also be sufficiently large to accommodate 100 L of liquid crystal material.

此種容器本體2較佳為由以鈦為主成分之素材形成。藉由利用以鈦為主成分之材料形成容器本體2，能夠防止因與容器本體2長時間接觸而導致液晶材料變質。再者，於以鈦為主成分之素材中包含僅由鈦所構成之純鈦、含有除純鈦以外之物質之複合材料、及鈦合金。即，容器本體2可由純鈦形成，可由除純鈦以外混合有其他物質之複合材料形成，可由鈦合金形成。 Such a container main body 2 is preferably formed of a material whose main component is titanium. By forming the container body 2 with a material whose main component is titanium, it is possible to prevent the liquid crystal material from deteriorating due to prolonged contact with the container body 2. Furthermore, the material mainly composed of titanium includes pure titanium composed only of titanium, composite materials containing substances other than pure titanium, and titanium alloys. That is, the container body 2 may be formed of pure titanium, may be formed of a composite material mixed with other substances in addition to pure titanium, or may be formed of a titanium alloy.

腳部3係於載置本實施形態之液晶材料貯藏容器1之情形時抵接於載置面的部位，自下方支持容器本體2等。圖3係包含本實施形態之液晶材料貯藏容器1之腳部3之放大立體圖。腳部3設為上端設為開口端之有底圓筒形狀，且具有直接固定於容器本體2之周壁部3a、及與該周壁部3a之下端連接之底壁部3b。 The leg portion 3 is a portion that abuts on the placement surface when the liquid crystal material storage container 1 of this embodiment is placed, and supports the container body 2 and the like from below. FIG. 3 is an enlarged perspective view of the leg portion 3 of the liquid crystal material storage container 1 of this embodiment. The leg portion 3 has a bottomed cylindrical shape with an open upper end, and has a peripheral wall portion 3a directly fixed to the container body 2 and a bottom wall portion 3b connected to the lower end of the peripheral wall portion 3a.

周壁部3a係藉由將上端焊接於容器本體2之底部2b之外壁面而固定於容器本體2，且自側方包圍設置於容器本體2之底部2b之凹部2b1之全周。如圖2所示，該周壁部3a具有下端位於較凹部2b1之下端更下方之高度尺寸。即，周壁部3a自底部2b之外壁面延伸至較凹部2b1之下端更下方。底壁部3b設為於俯視下外周緣沿著周壁部3a之圓形狀，自下方覆蓋設置於容器本體2之底部2b之凹部2b1。該底壁部3b具有以俯視之中央部位於較外緣部更上方之方式彎曲之形狀。因此，於腳部3抵接於載置面之情形時，於底壁部3b之中央部與載置面之間形成空間，僅底壁部3b之外周緣與載置面抵接。如此，藉由使底壁部3b以中央部朝向上方凹陷之方式彎曲，與底壁部3b為平板之情形相比，能夠將本實施形態之液晶材料貯藏容器1穩定地載置於具有凹凸之載置面。 The peripheral wall portion 3a is fixed to the container body 2 by welding the upper end to the outer wall surface of the bottom portion 2b of the container body 2, and surrounds the entire circumference of the recessed portion 2b1 provided in the bottom portion 2b of the container body 2 from the side. As shown in Fig. 2, the peripheral wall portion 3a has a height dimension whose lower end is located below the lower end of the concave portion 2b1. That is, the peripheral wall portion 3a extends from the outer wall surface of the bottom portion 2b below the lower end of the recessed portion 2b1. The bottom wall portion 3b is formed in a circular shape of the outer peripheral edge along the peripheral wall portion 3a in a plan view, and covers the recessed portion 2b1 provided in the bottom portion 2b of the container body 2 from below. The bottom wall portion 3b has a shape that is curved so that the center portion in a plan view is located above the outer edge portion. Therefore, when the leg portion 3 is in contact with the placement surface, a space is formed between the center portion of the bottom wall portion 3b and the placement surface, and only the outer periphery of the bottom wall portion 3b is in contact with the placement surface. In this way, by bending the bottom wall portion 3b so that the center portion is recessed upward, compared with the case where the bottom wall portion 3b is a flat plate, the liquid crystal material storage container 1 of this embodiment can be stably placed on a concave-convex surface. Placement surface.

此種腳部3係作為於容器本體2之外部(外側)覆蓋設置於容器本 體2之底部2b之凹部2b1的保護壁而發揮功能。如此作為保護壁而發揮功能之腳部3成為自側方包圍凹部2b1之全周並且自容器本體2之底部2b之外壁面延伸至較凹部2b1之下端更下方的圍壁。根據該腳部3，以自側方及下方覆蓋凹部2b1之方式配置，能夠防止異物自外側與凹部2b1接觸。 Such leg portion 3 functions as a protective wall covering the recessed portion 2b1 provided in the bottom portion 2b of the container body 2 on the outside (outside) of the container body 2. As shown in FIG. The leg part 3 which functions as a protective wall in this way becomes a surrounding wall which surrounds the whole periphery of the recessed part 2b1 from the side, and extends from the outer wall surface of the bottom part 2b of the container main body 2 below the lower end of the recessed part 2b1. According to this leg part 3, it arrange|positions so that the recessed part 2b1 may be covered from the side and below, and it can prevent that a foreign matter contacts with the recessed part 2b1 from the outer side.

再者，腳部3之形成材料並無特別限定，可與容器本體2同樣地，由以鈦為主成分之素材形成。藉由利用與容器本體2相同之材料形成腳部3，而容易進行腳部3相對於容器本體2之接合，並且可抑制容器本體2與腳部3之接合部位之經時變化。 In addition, the forming material of the leg part 3 is not specifically limited, Like the container main body 2, it can be formed of the material whose main component is titanium. By forming the feet 3 with the same material as the container body 2, the feet 3 can be easily joined to the container body 2, and the time-dependent change of the junction between the container body 2 and the feet 3 can be suppressed.

蓋部4係將容器本體2之開口部2d封閉之構件，且利用緊固部6緊固於容器本體2。圖4係蓋部4之整體圖，(a)係俯視圖，(b)係縱向剖面圖。如該等圖所示，蓋部4具備蓋本體4a、液體輸送部4b、及氣體輸送部4c。 The lid 4 is a member that closes the opening 2d of the container body 2 and is fastened to the container body 2 by the fastening portion 6. Fig. 4 is an overall view of the cover 4, (a) is a plan view, and (b) is a longitudinal sectional view. As shown in these figures, the cover part 4 is equipped with the cover main body 4a, the liquid conveyance part 4b, and the gas conveyance part 4c.

蓋本體4a係直徑與容器本體2之凸緣2c3相同之圓板狀之構件，藉由利用緊固部6固定於凸緣2c3而直接將開口部2d封閉。於蓋本體4a，於在俯視下與設置於凸緣2c3之螺栓插通孔2c4重疊之位置形成有螺栓插通孔4a1。再者，於本實施形態中，於凸緣2c3於圓周方向上以等間隔離散地設置有4個螺栓插通孔2c4，因此，於蓋本體4a亦以相同間隔設置有4個螺栓插通孔4a1。設置於蓋本體4a之該等螺栓插通孔4a1設為與設置於凸緣2c3之螺栓插通孔2c4相同之直徑。 The lid body 4a is a disc-shaped member having the same diameter as the flange 2c3 of the container body 2, and is fixed to the flange 2c3 by the fastening portion 6 to directly close the opening 2d. In the cover body 4a, a bolt insertion hole 4a1 is formed at a position overlapping the bolt insertion hole 2c4 provided in the flange 2c3 in a plan view. Furthermore, in this embodiment, the flange 2c3 is provided with four bolt insertion holes 2c4 discretely at equal intervals in the circumferential direction. Therefore, the cover body 4a is also provided with four bolt insertion holes at the same interval. 4a1. The bolt insertion holes 4a1 provided in the cover body 4a are set to the same diameter as the bolt insertion holes 2c4 provided in the flange 2c3.

又，於蓋本體4a，於在俯視下，中央部設置有液體輸送部安裝孔4a2，於相對於液體輸送部安裝孔4a2進行位移之位置設置有氣體輸送部安裝孔4a3。液體輸送部安裝孔4a2係形成於與圖2所示之軸芯L重疊之位置之圓孔，於上下方向上貫通蓋本體4a。於該液體輸送部安裝孔4a2嵌入有液體輸送部4b之基部4b1。氣體輸送部安裝孔4a3係形成於在俯視下相對於液體輸送部安裝孔4a2於蓋本體4a之徑向上進行位移之位置的圓孔，於上下方向上貫通蓋本體4a。於該氣體輸送部安裝孔4a3嵌入有氣體輸送部4c之基部4c1。 Furthermore, in the cover body 4a, in a plan view, a liquid delivery portion mounting hole 4a2 is provided in the center, and a gas delivery portion mounting hole 4a3 is provided at a position displaced relative to the liquid delivery portion mounting hole 4a2. The liquid conveying portion mounting hole 4a2 is a circular hole formed at a position overlapping with the shaft core L shown in FIG. 2, and penetrates the cover body 4a in the vertical direction. The base part 4b1 of the liquid conveyance part 4b is fitted in this liquid conveyance part mounting hole 4a2. The gas delivery portion mounting hole 4a3 is a circular hole formed at a position displaced in the radial direction of the cover body 4a with respect to the liquid delivery portion mounting hole 4a2 in a plan view, and penetrates the cover body 4a in the vertical direction. The base part 4c1 of the gas conveyance part 4c is fitted in this gas conveyance part mounting hole 4a3.

液體輸送部4b係於將液晶材料取出至容器本體2外部之情形時，將貯藏於容器本體2之液晶材料向外部送出之部位。圖5係包含液體輸送部4b及氣體輸送部4c之圖4之區域A之放大圖。如該圖所示，液體輸送部4b具備基部4b1、墊片4b2、液體輸送管4b3、及蓋體4b4。 The liquid conveying portion 4b is a part where the liquid crystal material stored in the container body 2 is sent to the outside when the liquid crystal material is taken out of the container body 2. Fig. 5 is an enlarged view of the area A of Fig. 4 including the liquid conveying portion 4b and the gas conveying portion 4c. As shown in this figure, the liquid conveyance part 4b is equipped with the base part 4b1, the gasket 4b2, the liquid conveyance tube 4b3, and the cover 4b4.

液體輸送部4b之基部4b1係嵌入至液體輸送部安裝孔4a2之圓柱狀之構件，且於俯視下，在中央部形成有上下貫通之貫通孔4b5。該基部4b1係藉由焊接或螺合等將下部與蓋本體4a接合，且使上部向較蓋本體4a更上方突出。又，於基部4b1之上部之外周面形成有用以使蓋體4b4螺合之公螺紋部4b6。進而，於基部4b1之下部之內周面形成有用以將液體輸送管4b3螺合之母螺紋部4b7。 The base portion 4b1 of the liquid conveying portion 4b is a cylindrical member inserted into the liquid conveying portion mounting hole 4a2, and in a plan view, a through hole 4b5 penetrating vertically is formed in the center portion. The base part 4b1 joins the lower part and the cover main body 4a by welding, screwing, etc., and the upper part protrudes above the cover main body 4a. In addition, a male screw portion 4b6 for screwing the lid body 4b4 is formed on the outer peripheral surface of the upper portion of the base portion 4b1. Furthermore, a female screw part 4b7 for screwing the liquid conveying pipe 4b3 is formed on the inner peripheral surface of the lower part of the base part 4b1.

再者，設置於基部4b1之貫通孔4b5係除了下部以外，設定為直徑與液體輸送管4b3之內徑相同。又，貫通孔4b5係使下部之區域相對於上部之區域擴徑，且於該經擴徑之部位形成有母螺紋部4b7。此種貫通孔4b5下部之區域係以與液體輸送管4b3之管厚尺寸相同之量相對於上部之區域擴徑。藉此，螺合於基部4bl之液體輸送管4b3之內壁面與貫通孔4b5之內壁面於俯視下重疊。 In addition, the through hole 4b5 provided in the base 4b1 is set to have the same diameter as the inner diameter of the liquid conveying pipe 4b3 except for the lower part. In addition, the through hole 4b5 expands the diameter of the lower region with respect to the upper region, and a female thread portion 4b7 is formed at the enlarged diameter portion. The lower area of the through hole 4b5 is enlarged with respect to the upper area by the same amount as the thickness of the liquid conveying pipe 4b3. Thereby, the inner wall surface of the liquid delivery pipe 4b3 screwed to the base 4b1 and the inner wall surface of the through hole 4b5 overlap in a plan view.

墊片4b2係以配置於設置在基部4b1之貫通孔4b5之經擴徑之區域(下部區域)之最上端的方式內嵌於貫通孔4b5之內部，且抵接於液體輸送管4b3之上端。墊片4b2係於中央具有開口之環狀之密封構件，且設定為開口直徑與液體輸送管4b3之內徑相同。此種墊片4b2防止液晶於基部4b1與液體輸送管4b3之邊界部分漏出。再者，亦可採用不設置墊片4b2之構成。於採用此種構成之情形時，例如藉由焊接或接著等將基部4b1與液體輸送管4b3接合，使基部4b1與液體輸送管4b3一體化。 The gasket 4b2 is inserted into the through hole 4b5 so as to be arranged at the uppermost end of the enlarged diameter region (lower region) of the through hole 4b5 of the base 4b1, and abuts against the upper end of the liquid delivery tube 4b3. The gasket 4b2 is a ring-shaped sealing member with an opening in the center, and the opening diameter is set to be the same as the inner diameter of the liquid delivery pipe 4b3. The spacer 4b2 prevents the liquid crystal from leaking out of the boundary portion between the base 4b1 and the liquid delivery tube 4b3. Furthermore, it is also possible to adopt the structure which does not provide the spacer 4b2. In the case of adopting such a configuration, the base 4b1 and the liquid conveying pipe 4b3 are joined by welding or bonding, for example, to integrate the base 4b1 and the liquid conveying pipe 4b3.

液體輸送管4b3係於上端部之外周面形成有公螺紋部4b8之直管，藉由公螺紋部4b8與形成於基部4b1之母螺紋部4b7螺合而固定於基部4b1。該液體輸送管4b3之下端位於由設置在容器本體2之底部2b之凹部2b1包圍之空 間(液晶材料積存之空間)。此種液體輸送管4b3將貯藏於容器本體2之液晶材料朝向容器本體2之外部引導。 The liquid conveying pipe 4b3 is a straight pipe with a male screw part 4b8 formed on the outer peripheral surface of the upper end part, and is fixed to the base part 4b1 by screwing the male screw part 4b8 with the female screw part 4b7 formed on the base part 4b1. The lower end of the liquid delivery pipe 4b3 is located in a space surrounded by a recess 2b1 provided at the bottom 2b of the container body 2 (a space where the liquid crystal material is stored). Such a liquid delivery pipe 4b3 guides the liquid crystal material stored in the container body 2 toward the outside of the container body 2.

又，於本實施形態之液晶材料貯藏容器1中，如圖5所示，基部4b1之貫通孔4b5之內壁面、墊片4b2之開口之內壁面、及液體輸送管4b3之內壁面係於同一平面連續。因此，可不阻礙依次由液體輸送管4b3、墊片4b2之開口、貫通孔4b5引導之液晶材料之流動，使液晶材料順利地流動。 In addition, in the liquid crystal material storage container 1 of this embodiment, as shown in FIG. 5, the inner wall surface of the through hole 4b5 of the base 4b1, the inner wall surface of the opening of the spacer 4b2, and the inner wall surface of the liquid delivery pipe 4b3 are in the same The plane is continuous. Therefore, the flow of the liquid crystal material guided by the liquid conveying tube 4b3, the opening of the spacer 4b2, and the through hole 4b5 in this order can not be hindered, and the liquid crystal material can flow smoothly.

蓋體4b4係具有與設置於基部4b1之上部之公螺紋部4b6螺合之母螺紋部4b9，且藉由母螺紋部4b9與公螺紋部4b6螺合而將基部4b1之貫通孔4b5封閉的構件。該蓋體4b4形成為相對於基部4b1裝卸自如，於將液晶材料自容器本體2之內部取出之情形時自基部4b1脫離。 The cover 4b4 is a member having a female thread part 4b9 screwed with a male thread part 4b6 provided on the upper part of the base part 4b1, and a member that closes the through hole 4b5 of the base part 4b1 by screwing the female thread part 4b9 with the male thread part 4b6 . The lid 4b4 is formed so as to be detachable from the base 4b1, and is detached from the base 4b1 when the liquid crystal material is taken out from the inside of the container body 2.

氣體輸送部4c係於將液晶材料取出至容器本體2外部之情形時用以向容器本體2之內部供給惰性氣體的部位。藉由通過氣體輸送部4c將惰性氣體供給至容器本體2之內部，容器本體2之內壓上升，從而將貯藏於容器本體2之液晶材料通過液體輸送部4b而向外部送出。如圖5所示，該氣體輸送部4c具有基部4c1、及蓋體4c2。再者，通過氣體輸送部4c供給至容器本體2之內部之氣體不限於惰性氣體。例如亦可將高純度空氣或大氣通過氣體輸送部4c供給至容器本體2之內部。 The gas delivery part 4c is a part for supplying an inert gas to the inside of the container body 2 when the liquid crystal material is taken out of the container body 2. The inert gas is supplied to the inside of the container body 2 through the gas conveying part 4c, and the internal pressure of the container body 2 rises, so that the liquid crystal material stored in the container body 2 is sent to the outside through the liquid conveying part 4b. As shown in FIG. 5, this gas conveyance part 4c has the base part 4c1, and the cover body 4c2. In addition, the gas supplied to the inside of the container body 2 through the gas conveying portion 4c is not limited to an inert gas. For example, high-purity air or atmospheric air may be supplied to the inside of the container body 2 through the gas delivery part 4c.

氣體輸送部4c之基部4c1係嵌入至氣體輸送部安裝孔4a3之圓柱狀之構件，且於俯視下，在中央部形成有上下貫通之貫通孔4c3。該基部4c1係藉由焊接或螺合等將下部與蓋本體4a接合，且使上部向較蓋本體4a更上方突出。又，於基部4c1之上部之外周面形成有用以使蓋體4c2螺合之公螺紋部4c4。 The base portion 4c1 of the gas delivery portion 4c is a cylindrical member inserted into the gas delivery portion mounting hole 4a3, and in a plan view, a through hole 4c3 penetrating vertically is formed in the center portion. The base part 4c1 joins the lower part and the cover main body 4a by welding, screwing, etc., and the upper part protrudes above the cover main body 4a. In addition, a male screw portion 4c4 for screwing the lid body 4c2 is formed on the outer peripheral surface of the upper portion of the base portion 4c1.

蓋體4c2係具有與設置於基部4c1之上部之公螺紋部4c4螺合之母螺紋部4c5，且藉由母螺紋部4c5與公螺紋部4c4螺合而將基部4c1之貫通孔4c3封閉的構件。該蓋體4c2形成為相對於基部4c1裝卸自如，於向容器本體2之內部供 給惰性氣體之情形時自基部4c1脫離。 The cover 4c2 is a member having a female thread part 4c5 screwed with a male thread part 4c4 provided on the upper part of the base part 4c1, and a member that closes the through hole 4c3 of the base part 4c1 by screwing the female thread part 4c5 with the male thread part 4c4 . The lid 4c2 is formed so as to be detachable from the base 4c1, and is detached from the base 4c1 when the inert gas is supplied to the inside of the container body 2.

返回至圖2，蓋部用封材5嵌合於設置在容器本體2之凸緣2c3之上表面之環狀的槽。該蓋部用封材5例如係由即便於與液晶材料接觸之情形時亦不會使自身及液晶材料變質的材料形成。此種蓋部用封材5係自上下方向夾於蓋部4之蓋本體4a與容器本體2之凸緣2c3之間，防止液晶材料自蓋部4與容器本體2之邊界部分漏出。 Returning to FIG. 2, the lid sealing material 5 is fitted into an annular groove provided on the upper surface of the flange 2c3 of the container body 2. The sealing material 5 for the cover part is formed of, for example, a material that does not change itself and the liquid crystal material even when it comes into contact with the liquid crystal material. This kind of lid sealing material 5 is sandwiched between the lid body 4a of the lid 4 and the flange 2c3 of the container body 2 from the up and down direction to prevent the liquid crystal material from leaking from the boundary portion between the lid 4 and the container body 2.

緊固部6係用以將蓋部4緊固於容器本體2之構件，且由螺栓6a與螺帽6b構成。緊固部6設置與設置於蓋本體4a之螺栓插通孔4a1相同之數量(即，與設置於容器本體2之凸緣2c3之螺栓插通孔2c4相同之數量)。螺栓6a插通於上下重疊配置之螺栓插通孔4a1與螺栓插通孔2c4。又，螺帽6b螺合於插通在螺栓插通孔4a1與螺栓插通孔2c4之螺栓6a之下端。藉由自上下方向被此種螺栓6a之頭部與螺帽6b夾住，而將蓋部4緊固於容器本體2。再者，亦可藉由夾件機構代替緊固部6將蓋本體4a緊固於凸緣2c3。 The fastening portion 6 is a member used to fasten the lid portion 4 to the container body 2, and is composed of a bolt 6a and a nut 6b. The fastening portion 6 is provided in the same number as the bolt insertion holes 4a1 provided in the lid body 4a (that is, the same number as the bolt insertion holes 2c4 provided in the flange 2c3 of the container body 2). The bolt 6a is inserted into the bolt insertion hole 4a1 and the bolt insertion hole 2c4 arranged one above the other. In addition, the nut 6b is screwed to the lower end of the bolt 6a inserted in the bolt insertion hole 4a1 and the bolt insertion hole 2c4. The cap 4 is fastened to the container body 2 by being sandwiched between the head of the bolt 6a and the nut 6b from the up and down direction. Furthermore, it is also possible to fasten the cover body 4a to the flange 2c3 by a clamping mechanism instead of the fastening part 6.

此種構成之本實施形態之液晶材料貯藏容器1係藉由容器本體2之製作、腳部3對於容器本體2之接合、蓋部4對於容器本體2之安裝而製造。例如，容器本體2之製作係藉由如下步驟而進行，即，如圖6之包含容器本體2之分解立體圖所示般將容器本體2分為3個部分，於形成各部分後進行焊接。 The liquid crystal material storage container 1 of the present embodiment having such a structure is manufactured by manufacturing the container body 2, joining the legs 3 to the container body 2, and attaching the lid 4 to the container body 2. For example, the production of the container body 2 is carried out by the following steps, that is, as shown in the exploded perspective view of the container body 2 in FIG.

具體而言，例如，將容器本體2如圖6所示般分為上下端設為開口端之圓筒狀之中央部10、包含開口部2d之上端部11、及包含底部2b之下端部12之3個部分，形成各部分。其後，藉由TIG焊接等將上端部11接合於中央部10之上端，藉由TIG焊接等將下端部12接合於中央部10之下端。如此，於將容器本體2分為3個部分而形成之情形時，能夠使焊縫僅為2個。因此，能夠將具有些許包含異物而使液晶材料變質之可能性的焊縫抑制為最小限度。再者，焊縫亦可不為2個。例如，於使板材彎曲將端部彼此焊接而成形圓筒狀之中央部10之情形 時，於中央部10縱向形成焊縫。於此種情形時，即便容器本體2係由中央部10、上端部11、及下端部12之3個部分形成，焊縫亦成為3個。 Specifically, for example, as shown in FIG. 6, the container body 2 is divided into a cylindrical central portion 10 whose upper and lower ends are open ends, an upper end portion 11 including an opening portion 2d, and a lower end portion 12 including a bottom portion 2b. The three parts form each part. Thereafter, the upper end portion 11 is joined to the upper end of the central portion 10 by TIG welding or the like, and the lower end portion 12 is joined to the lower end of the central portion 10 by TIG welding or the like. In this way, when the container body 2 is divided into three parts and formed, only two welds can be made. Therefore, it is possible to minimize weld seams that may contain foreign substances to change the quality of the liquid crystal material. Furthermore, the number of welds may not be two. For example, when a plate is bent and the ends are welded to each other to form a cylindrical central portion 10, a weld is formed in the longitudinal direction of the central portion 10. In this case, even if the container body 2 is formed by three parts of the center part 10, the upper end part 11, and the lower end part 12, there will be three welds.

進而，藉由將容器本體2分為如上所述之中央部10、上端部11、及下端部12而形成，能夠分為具有相對複雜形狀之部位(具有口部2c2之上端部11與具有凹部2b1之下端部12)、及具有相對簡單形狀之部位(單純之圓筒狀之中央部10)而形成，容器本體2之製作變得容易。 Furthermore, by dividing the container body 2 into the central part 10, the upper end part 11, and the lower end part 12 as described above, it can be divided into parts having a relatively complicated shape (with the mouth part 2c2, the upper end part 11 and the upper end part 11 with the concave part). 2b1 lower end portion 12) and a relatively simple shape (a simple cylindrical central portion 10) are formed, and the production of the container body 2 becomes easy.

再者，亦可視需要對容器本體2之表面實施研磨處理。但是，考慮殘存物對液晶材料造成影響之可能性，較佳為不進行拋光研磨，而進行電解研磨或化學研磨。又，於由以鈦為主成分之素材形成容器本體2之情形時，亦可考慮到電解研磨較難，因此，於該情形時亦可僅進行化學研磨。 Furthermore, the surface of the container body 2 may be subjected to grinding treatment as needed. However, considering the possibility that the residue may affect the liquid crystal material, it is preferable to perform electrolytic polishing or chemical polishing instead of polishing. In addition, when the container body 2 is formed from a material whose main component is titanium, electrolytic polishing may be difficult, and therefore, only chemical polishing may be performed in this case.

藉由TIG焊接等將腳部3接合於以此方式製作之容器本體2。此時，較佳為避開中央部10與下端部12之接合部位而將腳部3接合於容器本體2。如此，藉由避開中央部10與下端部12之接合部位而將腳部3接合於容器本體2，能夠防止接合部位重疊，從而提高接合品質或強度。 The leg 3 is joined to the container body 2 manufactured in this way by TIG welding or the like. At this time, it is preferable to avoid the junction between the central portion 10 and the lower end portion 12 and to join the leg portion 3 to the container body 2. In this way, by avoiding the junction between the central portion 10 and the lower end portion 12 and joining the leg portion 3 to the container body 2, it is possible to prevent the joining portion from overlapping, thereby improving the joining quality and strength.

再者，於製作容器本體2時或接合腳部3時進行TIG焊接之情形時，理想的是於惰性氣體環境下進行以削減焊接部位中之雜質。進而，接合腳部3時，理想的是以將惰性氣體封入至由腳部3與容器本體2所包圍之空間之方式進行接合。藉此，即便經過長時間後，亦能夠防止因外部氣體等而導致容器本體2之底部2b劣化，而能夠長期維持凹部2b1之形狀。 Furthermore, when TIG welding is performed when the container body 2 is manufactured or when the legs 3 are joined, it is ideal to perform TIG welding under an inert gas environment to reduce impurities in the welding part. Furthermore, when joining the leg part 3, it is desirable to join so that an inert gas may be enclosed in the space enclosed by the leg part 3 and the container main body 2. Thereby, even after a long period of time, deterioration of the bottom portion 2b of the container body 2 due to external air or the like can be prevented, and the shape of the recessed portion 2b1 can be maintained for a long period of time.

又，於將液晶材料裝進至此種本實施形態之液晶材料貯藏容器1之情形時，於將蓋部4自容器本體2卸除之狀態下，視需要利用酸等將容器本體2之內部洗淨，之後於惰性氣體環境等中，將液晶材料自開口部2d供給至容器本體2之內部。其後，於在容器本體2之內部填充有惰性氣體之狀態下，利用緊固部6將蓋部4關閉。 In addition, when the liquid crystal material is loaded into the liquid crystal material storage container 1 of this embodiment, with the lid 4 removed from the container body 2, the inside of the container body 2 is washed with acid or the like as necessary. After cleaning, the liquid crystal material is supplied to the inside of the container body 2 from the opening 2d in an inert gas atmosphere or the like. After that, in a state in which the inside of the container body 2 is filled with an inert gas, the lid 4 is closed by the fastening portion 6.

另一方面，於自本實施形態之液晶材料貯藏容器1將液晶材料取出之情形時，將液體輸送部4b之蓋體4b4卸除，並將接收側之裝置之液體輸送管連接於液體輸送部4b之基部4b1。又，將氣體輸送部4c之蓋體4c2卸除，並將氣體供給裝置連接於氣體輸送部4c之基部4c1。然後，自氣體供給裝置向容器本體2之內部供給氣體，而將液晶材料向容器本體2之外部送出。 On the other hand, when the liquid crystal material is taken out from the liquid crystal material storage container 1 of this embodiment, the cover 4b4 of the liquid conveying part 4b is removed, and the liquid conveying tube of the device on the receiving side is connected to the liquid conveying part The base 4b1 of 4b. Furthermore, the cover 4c2 of the gas conveying part 4c is removed, and the gas supply device is connected to the base part 4c1 of the gas conveying part 4c. Then, gas is supplied to the inside of the container body 2 from the gas supply device, and the liquid crystal material is sent to the outside of the container body 2.

再者，作為貯藏於本實施形態之液晶材料貯藏容器1之液晶材料，並無特別限定，例如可列舉如國際公開第2015/159678號中所列舉之含有導入有氟基之液晶化合物之液晶組成物。 Furthermore, the liquid crystal material stored in the liquid crystal material storage container 1 of this embodiment is not particularly limited. For example, a liquid crystal composition containing a liquid crystal compound introduced with a fluorine group as listed in International Publication No. 2015/159678 Things.

如以上說明之本實施形態之液晶材料貯藏容器1具備：容器本體2，其於上部具有開口部2d，且於底部2b之一部分具有朝向下方凹陷之凹部2b1；及蓋部4，其能夠將容器本體2之開口部2d開閉。根據如本實施形態之液晶材料貯藏容器1，於容器本體2之底部2b形成有朝向下方凹陷之凹部2b1。該凹部2b1係向較周圍區域2b2之上表面更下方凹陷而形成。因此，殘存於容器本體2底部2b之液晶材料積存於凹部2b1。即，根據本實施形態之液晶材料貯藏容器1，能夠將殘存於底部2b之液晶材料局部地聚集至凹部2b1。因此，與液晶材料殘存於容器本體2之底部2b之較大範圍的情形相比，容易自容器本體2取出殘存之液晶材料。由此，根據本實施形態之液晶材料貯藏容器1，能夠減少難以自容器本體2取出之液晶材料而有效利用液晶材料。 As described above, the liquid crystal material storage container 1 of the present embodiment includes: a container body 2 having an opening 2d at the upper part and a concave part 2b1 recessed downward in a part of the bottom part 2b; and a lid 4 that can hold the container The opening 2d of the main body 2 opens and closes. According to the liquid crystal material storage container 1 of this embodiment, the bottom 2b of the container body 2 is formed with a recess 2b1 that is recessed downward. The recess 2b1 is formed by being recessed below the upper surface of the surrounding area 2b2. Therefore, the liquid crystal material remaining in the bottom 2b of the container body 2 is accumulated in the recess 2b1. That is, according to the liquid crystal material storage container 1 of the present embodiment, the liquid crystal material remaining on the bottom portion 2b can be partially collected in the concave portion 2b1. Therefore, compared with a case where the liquid crystal material remains in a larger area of the bottom portion 2b of the container body 2, the remaining liquid crystal material can be easily taken out from the container body 2. Therefore, according to the liquid crystal material storage container 1 of the present embodiment, it is possible to reduce the liquid crystal material that is difficult to take out from the container body 2 and effectively use the liquid crystal material.

又，於本實施形態之液晶材料貯藏容器1中，於俯視下容器本體2之底部2b為圓形，且於底部2b之中央配置有凹部2b1。因此，能夠設為如下構成，即，使自凹部2b1至底部2b之外緣部為止之距離均等，而凹部2b1距底部2b之任一部位均不過遠。因此，能夠將殘存於底部2b上之液晶材料穩定地聚集至凹部2b1。又，液晶材料局部地聚集至在俯視下容器本體2之中央。因此，藉由將液體輸送管4b3配置於蓋本體4a之中央，可無關於俯視下之蓋本體4a之旋轉方向之 朝向，而容易地進行液體輸送管4b3與液晶材料聚集區域之位置對準。 In addition, in the liquid crystal material storage container 1 of this embodiment, the bottom 2b of the container body 2 is circular in a plan view, and a recess 2b1 is arranged in the center of the bottom 2b. Therefore, it can be set as the structure in which the distance from the recessed part 2b1 to the outer edge part of the bottom part 2b is made equal, and the recessed part 2b1 is not too far away from any part of the bottom part 2b. Therefore, the liquid crystal material remaining on the bottom portion 2b can be stably collected in the concave portion 2b1. In addition, the liquid crystal material is locally gathered to the center of the container body 2 in a plan view. Therefore, by arranging the liquid delivery tube 4b3 in the center of the cover body 4a, the position of the liquid delivery tube 4b3 and the liquid crystal material gathering area can be easily aligned regardless of the orientation of the rotation direction of the cover body 4a in a plan view.

又，於本實施形態之液晶材料貯藏容器1中，容器本體2之底部2b之上表面設為隨著朝向凹部2b1而下降之傾斜面。因此，能夠將殘存於凹部2b1之周圍區域2b2之液晶材料朝向凹部2b1引導，而能夠更確實地將液晶材料聚集至凹部2b1。 Moreover, in the liquid crystal material storage container 1 of this embodiment, the upper surface of the bottom part 2b of the container main body 2 is set as the inclined surface which descends toward the recessed part 2b1. Therefore, the liquid crystal material remaining in the peripheral area 2b2 of the concave portion 2b1 can be guided toward the concave portion 2b1, and the liquid crystal material can be more surely gathered in the concave portion 2b1.

又，於本實施形態之液晶材料貯藏容器1中，具有腳部3，該腳部3作為固定於容器本體2之外壁面且於容器本體2之外側覆蓋凹部2b1之保護壁而發揮功能。因此，能夠防止凹部2b1與外部之構件等接觸，而能夠防止凹部2b1發生變形等。因此，能夠穩定地將液晶材料聚集至凹部2b1。又，藉由將腳部3與容器本體2之底部2b之間之空間設為密閉空間，能夠防止水等異物自外部滲入至該空間，而能夠防止容器本體2之底部2b之劣化。 In addition, the liquid crystal material storage container 1 of the present embodiment has leg portions 3 that function as a protective wall that is fixed to the outer wall surface of the container body 2 and covers the recessed portion 2b1 on the outer side of the container body 2. Therefore, it is possible to prevent the recessed portion 2b1 from contacting external members and the like, and it is possible to prevent the recessed portion 2b1 from being deformed or the like. Therefore, it is possible to stably gather the liquid crystal material to the concave portion 2b1. In addition, by making the space between the leg portion 3 and the bottom portion 2b of the container body 2 a closed space, it is possible to prevent foreign matter such as water from penetrating into the space from the outside, and to prevent the bottom portion 2b of the container body 2 from deteriorating.

又，於本實施形態之液晶材料貯藏容器1中，腳部3成為自側方包圍凹部2b1之全周並且自容器本體2之底部2b之外壁面延伸至較凹部2b1之下端更下方的圍壁。因此，即便於將腳部3載置於載置面之情形時，亦能夠防止凹部2b1與載置面接觸。因此，能夠防止凹部2b1發生變形等，從而能夠穩定地將液晶材料聚集至凹部2b1。 In addition, in the liquid crystal material storage container 1 of this embodiment, the leg portion 3 becomes a surrounding wall that surrounds the entire circumference of the recess 2b1 from the side and extends from the outer wall surface of the bottom 2b of the container body 2 to below the lower end of the recess 2b1 . Therefore, even when the leg portion 3 is placed on the placement surface, it is possible to prevent the recessed portion 2b1 from contacting the placement surface. Therefore, it is possible to prevent deformation or the like of the concave portion 2b1, so that the liquid crystal material can be stably collected in the concave portion 2b1.

以上，一面參照隨附圖式，一面對本發明之較佳之實施形態進行了說明，但本發明不限定於上述實施形態係不言而喻的。於上述實施形態中示出之各構成構件之各形狀或組合等係一例，可於不脫離本發明之目的之範圍內基於設計要求等進行各種變更。 Above, the preferred embodiments of the present invention have been described with reference to the accompanying drawings, but it goes without saying that the present invention is not limited to the above-mentioned embodiments. Each shape or combination of each component shown in the above-mentioned embodiment is an example, and various changes can be made based on design requirements and the like without departing from the purpose of the present invention.

例如，於上述實施形態中，對在容器本體2之底部2b設置有1個凹部2b1之構成進行了說明。然而，本發明並不限定於此，亦可採用設置複數個凹部2b1之構成。 For example, in the above-mentioned embodiment, the structure which provided the one recessed part 2b1 in the bottom part 2b of the container main body 2 was demonstrated. However, the present invention is not limited to this, and a configuration in which a plurality of recesses 2b1 are provided may also be adopted.

又，於上述實施形態中，對將凹部2b1配置於底部2b之中央之構 成進行了說明。然而，本發明並不限定於此，亦可於自中央進行位移之位置形成凹部2b1。 In addition, in the above-mentioned embodiment, the structure in which the recessed portion 2b1 is arranged in the center of the bottom portion 2b has been described. However, the present invention is not limited to this, and the recess 2b1 may be formed at a position displaced from the center.

又，於上述實施形態中，對使用腳部3作為保護凹部2b1之本發明之保護壁之構成進行了說明。然而，本發明並不限定於此，亦可採用與腳部分開地設置保護壁之構成。 Moreover, in the above-mentioned embodiment, the structure of the protective wall of this invention which uses the leg part 3 as a protection recessed part 2b1 was demonstrated. However, the present invention is not limited to this, and a configuration in which a protective wall is provided separately from the foot may also be adopted.

又，於上述實施形態中，對由以鈦為主成分之素材形成容器本體2之構成進行了說明。然而，本發明並不限定於此，可由SUS304、SUS316、SUS316L之不鏽鋼等形成容器本體2。又，亦可採用於不鏽鋼構成之容器本體2表面塗佈以鈦為主成分之素材的構成。 Moreover, in the above-mentioned embodiment, the structure which forms the container main body 2 from the material which consists of titanium as a main component was demonstrated. However, the present invention is not limited to this, and the container body 2 can be formed of stainless steel such as SUS304, SUS316, SUS316L, or the like. In addition, it is also possible to adopt a structure in which a material whose main component is titanium is coated on the surface of the container body 2 made of stainless steel.

又，於上述實施形態中，採用使用下端面較為平坦之液體輸送管4b3之構成。然而，本發明並不限定於此。例如亦可設為如圖7(a)所示之於下端形成有朝向側方開口之開口部4d1之液體輸送管4d、如圖7(b)所示之使下端傾斜之液體輸送管4e、或如圖7(c)所示之下端朝向側方彎曲之液體輸送管4f。藉由採用該等構成，即便於液體輸送管與底部2b接觸之情形時，亦能夠防止液體輸送管堵塞，而能夠更確實地將液晶材料取出至外部。 Moreover, in the above-mentioned embodiment, the structure using the liquid conveyance pipe 4b3 with a relatively flat lower end surface is adopted. However, the present invention is not limited to this. For example, as shown in Fig. 7(a), a liquid conveying pipe 4d having an opening 4d1 that opens to the side is formed at the lower end, and a liquid conveying pipe 4e having an inclined lower end as shown in Fig. 7(b). Or, as shown in Fig. 7(c), the liquid conveying pipe 4f whose lower end is bent to the side. By adopting these structures, even when the liquid conveying pipe is in contact with the bottom portion 2b, the liquid conveying pipe can be prevented from being clogged, and the liquid crystal material can be taken out more reliably.

又，於上述實施形態中，係設為液體輸送部4b之基部4b1與氣體輸送部4c之基部4c1為相同之外徑者而圖示。然而，亦可使液體輸送部4b之基部4b1與氣體輸送部4c之基部4c1之外徑不同。藉此，能夠防止於將液晶材料取出之情形時誤將氣體供給部與液晶材料之接收側之裝置連接。 In addition, in the above-mentioned embodiment, the base part 4b1 of the liquid conveyance part 4b and the base part 4c1 of the gas conveyance part 4c are shown in figure as the same outer diameter. However, the outer diameter of the base 4b1 of the liquid conveying portion 4b and the base 4c1 of the gas conveying portion 4c may be different. Thereby, it is possible to prevent the gas supply part from being accidentally connected to the device on the receiving side of the liquid crystal material when the liquid crystal material is taken out.
